Bought a new car this morning

To begin, you need to verify if its getting spark at the plugs when its cranking but not starting.
Does it have electronic ignition or points?
Then, see if its getting fuel when its not starting?
Does it have an electric or mechanical fuel pump?
These facts will begin to tell the story.
I will be digging into it this coming week. Getting spark at the plugs. It is electronic but aftermarket, thinking I should get a pretty good zap but it kinda felt weak, getting fuel, mechanical fuel pump. Going to rest up a day and start the track down process. First thing I will be doing is shooting a bit of starting fluid into the carb if it is still only cranking. Then check wires and the electronic ignition box and see if I'm getting spark at the plugs.
